Fighting in Korea, Rex is assigned by his handler to watch over green soldiers going up against seasoned enemies. When the raw recruits brush off Rex as a pest, he "ghosts" ahead of the squad. He yanks tripwires, forces sentries and snipers to shoot, and exposes a tank. The squad thinks the enemy was careless, and Rex useless, but his handler knows otherwise.; Sent to a farm while his owners are away, Rex is ignored as a prize hunting dog is pampered for a grueling five-mile race. The family has bet the farm on the outcome. Villains sneak in by night and attack the dog, wounding it. So Rex runs the race and saves their family farm, and gets rewarded with pampering of his own!; Bobo finds the missing will of Carlton Meade and solves the murder.
